1. A Heat transfer rates are directly proportional to the difference in fluid densities which, in turn, is directly proportional to the temperature gradient.
2. B Heat transfer rates are inversely proportional to the difference in fluid densities which, in turn, is directly proportional to the temperature gradient.
3. C Heat transfer rates are directly proportional to the difference in fluid densities which, in turn, is inversely proportional to the temperature gradient.
4. D Heat transfer rates are inversely proportional to the difference in fluid densities which, in turn, is inversely proportional to the temperature gradient.
